Hi,

Firstly, I would recommend you spend a bit of time and workout RAID  - 
what it means and what it does.

Where it the raid metadata stored ? what kind of an hba is it ? what is 
the volume manager on there ? If you can answer those three questions, 
you can then workout what your options are.

Personally, the safest option is to go with with Ero has already pointed 
out, setup a new Vol, migrate your data.
